This study uncovers what issues are at stake in land use, land development, and regulations of two specific areas in south Louisiana that contain this type of wetland.
This is an educational project oriented toward development of methods and information related to planning and design for the use of wetland sites while still protecting them. A hypothesis is presented that a combination of education with land use guidelines, helpful resources and regulatory incentives may help slow the eradication of bogs in the southern United States and increase the awareness of the importance of these small isolated wetlands.
Although small in size, acid bogs function in important ways to help society and surrounding natural ecosystems. Land use practices and attitudes towards building on sensitive inland wetland sites were investigated to discover what role developers and homeowners play in their destruction. Case studies of several Louisiana home sites found homeowner awareness of the wetland, but not of its value and consequently little effort being put into acid bog preservation. Property rights issues, plus the complete lack of market value recognition for the benefits of small inland wetland sites, were found to be at the root of the conservation problem. Likewise, a survey of developers in south Louisiana uncovered a disinterest in plant community preservation. Results point towards attitudes that seem to be governed by short-term monetary gain from wetland land use. Outdated development practices (draining and filling) in sensitive sites contribute heavily to acid bog destruction. More importantly, wetlands are being destroyed due to a slow and confusing regulatory process as the regulations for them are being followed.
Guidelines and helpful resources are presented in order to lower development costs and facilitate acid bog conservation on individual sites. Moreover, findings indicate that an area wide effort is needed due to the unique connections that acid bogs have with underground water systems. Not only can improved design opportunities and higher property values be enjoyed through acid bog conservation, but cleaner and more available water for communities can also be achieved by developing properties in such a way as to protect the unique acid bog habitat.
